It's an interesting thing to do, just after GAFCON, and during the Lambeth Conference. I wouldn't have seen this in the summer of 2002, that's for certain.
I wrote another collect last week. I like to read them during the Prayers of the People (the intercessions), and I always have them approved by the Rector, since they are intercessions with particular theological content.
Loving God, you founded your Church on the cornerstone of Jesus Christ to experience and implement your plan for the world's redemption, and gave us the Scriptures and the Creeds to guide us in your Truth. Grant us the gift of your Spirit so that we would always continue in that religion which is both Catholic and Biblical.
Lord, in your mercy
Hear our prayer
